Abstract
A drive unit may be employed by an elevator system with vertical guide rails in two shafts, a horizontal guide rail that connects the vertical guide rails in the two shafts, independently movable elevator cars guided via guide rollers, and a rotatable rail segment configured to be transferred by the drive unit from a vertical alignment into a horizontal alignment so that the elevator cars may be transferred between shafts. The drive unit may include a first interface for at least indirectly fastening the rotatable rail segment to the drive unit, and a second interface for at least indirectly fastening the drive unit to a shaft wall in the first or second elevator shafts.”

1-18. (canceled)
A drive unit for an elevator system that comprises a first elevator shaft, a second elevator shaft, vertical guide rails in the first and second elevator shafts, a horizontal guide rail configured to connect the vertical guide rails in the first and second elevator shafts, elevator cars that are movable independent of one another along the vertical guide rails, a rotatable rail segment that is configured to be transferred by the drive unit from a vertical alignment into a horizontal alignment so that the elevator cars can be transferred from the vertical guide rails to the horizontal guide rail, the drive unit comprising:
- a first interface for at least indirectly fastening the rotatable rail segment to the drive unit;
- and
- a second interface for at least indirectly fastening the drive unit in the first elevator shaft or the second elevator shaft.
The drive unit of claim 26 wherein the electric motor unit comprises position sensors, wherein each position sensor determines a rotor position of the electric motor unit, wherein one of the position sensors is exclusively assigned to each of the at least three stand-alone inverter systems.
An elevator system comprising:
- a first elevator shaft;
- a second elevator shaft;
- vertical guide rails in the first and second elevator shafts;
- a horizontal guide rail configured to connect the vertical guide rails in the first and second elevator shafts;
- elevator cars that are movable independent of one another along the vertical guide rails;
- a drive unit that is disposed inside the first elevator shaft or the second elevator shaft in an intermediate space;
- and
- a rotatable rail segment that is configured to be transferred by the drive unit from a vertical alignment into a horizontal alignment so that the elevator cars can be transferred from the vertical guide rails to the horizontal guide rail, wherein the intermediate space where the drive unit is disposed is between a shaft wall and the rotatable rail segment.
